Local moms are giving birth to a grassroots movement promoting the one-night-only sneak preview of celebrity actress/host Ricki Lake's new movie, "The Business of Being Born" at the Tally Ho Theatre, 19 West Market St., Oct. 29, at 7:30 p.m. The film points out that some of the most traditional practices of contemporary obstetrics have everything to do with the convenience of the physician, but can actually make delivery more difficult for the mother. Doors open at 6:45 p.m. Tickets are $10. Visit www.tallyhotheatre.org.
